Hm. This version may be broken.

Please try the last production image from:

This could mean that X-Loader in NAND is broken.

getting "60" is a good sign.

That is ok.

Maybe something with the serial port settings (parity?).

Just put the

on a SD card and insert that. Then, power on with AUX button pressed. This
forces the boot ROM to ignore NAND and try the "MLO" on the SD card firstly.

You may even try this with your current card to find out if you can still boot
from SD.

If that does not work well, there may be a formatting problem with the FAT
partition. Or the SD card is broken.

To give you some more background what the Boot ROM does:

1. try X-Loader from Flash
2. try MLO from SD-card (if inserted and available)
3. try boot over USB (this is the full speed device you can see)
4. try serial boot (the "60" is what you see from the "ASIC ID" (which is just some binary bit pattern that happens to have some ASCII '6' and '0' inside).
